Example - Using the max DC charge current of 45 amps in a 24V system:
1. Multiply the charge current by the voltage:
45 Adc x 24 Vdc = 1,080 Wdc
2. Divide this by the charger efficiency (85% = 0.85):
1,080 Wdc ÷ 0.85 = 1,270 Wac
3. Divide this by the inverter voltage (120 or 240 Vac depending on inverter):
1,270 Wac ÷ 240Vac = 5.29 Aac
4. Round down because only whole numbers can be used as input, and the lower figure
ensures protection against over-charging the battery: 5 Aac
CAUTION: This calculation is for a single PHI battery, and can be increased proportionately with
the total number of batteries in parallel. i.e. Setting for Aac using three 24V batteries is (5.29 x
N
BATTERIES
= 15.88 Aac; round up to 16 Aac).
